Review on Axxess GMOS-LAN-034 GM Factory Integration Interface with OnStar and Chime Retention Module for 2006 and Up Select GM Vehicles by Dylan Baldwin

The product is working correctly. Works well with my 2009 Cobalt and I can keep the bells. The problem lies in the instructions that came with the product. The instructions did not mention reinforced and non-reinforced. The manual also doesn't mention which set of rear speaker wires to connect, or the fact that no amplification requires the speaker wires to be cut under the resistor. I had to search the internet for this information as my rear speakers were barely making any sound. Please update the instructions that came with the product.
